TESTING YOUR BLOOD GLUCOSE
Error messages
If you get an Er message on your screen rather than a result, see Understanding error and other messages in Section 7.
Unexpected test results
Refer to these cautions whenever your results are lower than, higher than, or otherwise not what you expect.
Read your result on the meter
Your blood glucose level appears on the display, along with the unit of
measure, and the date and time of the test. Blood glucose results are
automatically stored in the meter’s memory.
CAUTION: If you test at the low end of the operating range (6–44°C) and your glucose is high (over 180 mg/dL), the
reading on your meter may be lower than your actual glucose. In this situation, repeat the test in a warmer environment
with a new test strip as soon as possible.
WARNING: If mg/dL does not appear with the test result, contact your local LifeScan Representative. Use of
the wrong unit of measure may cause you to misinterpret your blood glucose level, and may lead to incorrect
treatment.
